WD4000FYYZ Write Cache Disabled

I’m running Unraid using this particular WD4000FYYZ 4TB Re drive as my parity drive. I try to run the command:

hdparm -W1 /dev/sdj

I get the following back:

setting drive write-caching to 1 (on)
write-caching =  0 (off)

This is a new bare OEM drive I purchased about 5 months ago. Is there a way I can get the write cache enabled? All the other drives in my array are functioning normally with the write cache enabled. What is going on?
